Overview
The LB11970RV is a motor driver of the single phase bipolar drive that a good direct PWM drive of the motor drive efficiency can come true easily.
It is most suitable for the power supply fan of the personal computer, CPU air conditioner fan drive.
Functions
• Single-phase full-wave drive (16V to 1.
2A output
transistor incorporated) • Variable speed function using thermistor input and external signal incorporated
→Enables silent and low-vibration variable speed control through direct PWM control with separately-excited upper Tr • Current limiter circuit (limit a...
